New Features

• 💥 New Form component 💥 creates a shallow wrapper of a <form> tag that allows redux-form to call the onSubmit function when a submit is triggered via a SUBMIT action or via the instance API. #2326 #2238 Kudos to @davidkpiano for the idea.
• New forceUnregisterOnUnmount config parameter that fixes some problems with wizard forms. #2310 #2231
• New selectors for submitting, submitSucceeded and submitFailed. #2289 #2173
• More control over how FormSection operates. #2329 #2271 #2274 When FormSection needs to wrap its children in a component, you may now:
  • Specify the type of component, e.g. div, section, etc.
  • Pass through props, e.g. className, style, to said component

Bug Fixes

• First call to validate was always receiving an empty object when enableReinitialize was true. #2296 #1901
• Change to allow undefined to be returned from sync validation. #2273 #2272
• Bind handlers to components. There were some unnecessary re-renders being caused by event handlers being created each time a field was rendered rather than using bound member methods. #2161 Kudos to @oreqizer for this major refactor.
